The Siemens 3VA5225-5EC41-0AA0 is a 4-pole molded-case circuit breaker from the SENTRON series, designed for robust system protection. It features a maximum rated operational current of 250A and a maximum operational voltage of 690V AC or 1000V DC. The breaker provides overload protection with an adjustable Ir of 250A and fixed short-circuit protection with an Ii range of 5 to 10 times the nominal current.
With a breaking capacity of 55 kA at 415V AC according to IEC 60947 and 35 kA at 480V AC according to UL 489, this circuit breaker ensures reliable protection against short circuits. It is suitable for HACR type applications and mounts on a DIN rail.
Key electrical endurance ratings include 8,000 switching cycles at 380/415V AC and 4,000 switching cycles at 690V AC. The mechanical service life is typically 20,000 switching cycles. The breaker operates with a TM230 overcurrent release and offers LI protection functionality.
